鼠标悬停时显示图像(在带有 jsfiddle 的工作示例中）

我发现了这个小提琴 http://jsfiddle.net/22sxotje/如果我将鼠标悬停在带有类 lochtonialcaress 的元素上，则会出现图像lochtonialcaress.png。

我如何更改此脚本以显示任何带有类名的元素的图像（类名.png），但没有图像classname.png则不显示任何

如果我复制它并仅更改类名，这是有效的，但是如何将它们连接在一起：

$(document).ready(function () {
    var yOff = 15;
    var xOff = -20;
    var pathToImage = "http://x.jupe.pl/lochtonialcaress.png";
    $(".lochtonialcaress").hover(function (e) {
        $("body").append("<p id='image-when-hovering-text'><img src='" + pathToImage + "'/></p>");
        $("#image-when-hovering-text")
            .css("position", "absolute")
            .css("top", (e.pageY - yOff) + "px")
            .css("left", (e.pageX + xOff) + "px")
            .fadeIn("fast");
    },
    function () {
        $("#image-when-hovering-text").remove();
    });
    $(".lochtonialcaress").mousemove(function (e) {
        $("#image-when-hovering-text")
            .css("top", (e.pageY - yOff) + "px")
            .css("left", (e.pageX + xOff) + "px");
    });
});
$(document).ready(function () {
    var yOff = 15;
    var xOff = -20;
    var pathToImage = "http://x.jupe.pl/vollsprotector.png";
    $(".vollsprotector").hover(function (e) {
        $("body").append("<p id='image-when-hovering-text'><img src='" + pathToImage + "'/></p>");
        $("#image-when-hovering-text")
            .css("position", "absolute")
            .css("top", (e.pageY - yOff) + "px")
            .css("left", (e.pageX + xOff) + "px")
            .fadeIn("fast");
    },
    function () {
        $("#image-when-hovering-text").remove();
    });
    $(".vollsprotector").mousemove(function (e) {
        $("#image-when-hovering-text")
            .css("top", (e.pageY - yOff) + "px")
            .css("left", (e.pageX + xOff) + "px");
    });
});

<p>This is my paragraph with a <a class="lochtonialcaress" href="#">very special hover</a> effect on the link.</p>

<p>The hovering works with every element that has <span class="no-image"> a class of <em>"text-hover-image"</em></span>
